i'm trying to get the radio to work on a computer at work, but on the "listen to my radio" page it doesn't have the little grey player with the play button and all that

what do i need to install to get it to work? It's already got flash, but that might be blocked somehow. I just don't know. And i know that it's not last.fm's problem because i can get it on this computer (although i don't have a soundcard)

Please help this pathetic and frightened idiot. PLEASE
